MSG NUM_COL ---------- ---------123.45 123.45 123.456 123.46 Notice how the number 123.456, with more than five digits, succeeded this time. That is because the scale we used in this example was used to round 123.456 to two digits, resulting in 123.46, and then 123.46 was validated against the precision, found to fit, and inserted. However, if we attempt the following insert, it fails: ops$tkyte@ORA10GR1> insert into t (msg,num_col) values ( '1234', 1234 ); insert into t (msg,num_col) values ( '1234', 1234 ) * ERROR at line 1: ORA-01438: value larger than specified precision allows for this column because the number 1234.00 has more than five digits in total. When you specify the scale of 2, at most three digits may be to the left of the decimal place and two to the right. Hence, that number does not fit. The NUMBER(5,2) column can hold all values between 999.99 and 999.99. It may seem strange to allow the scale to vary from 84 to 127. What purpose could a negative scale fulfill It allows you to round values to the left of the decimal place. Just as the NUMBER(5,2) rounded values to the nearest .01, so a NUMBER(5,-2) would round to the nearest 100, for example: ops$tkyte@ORA10GR1> create table t ( msg varchar2(10), num_col number(5,-2) ); Table created. ops$tkyte@ORA10GR1> insert into t (msg,num_col) values ( '123.45', 1 row created. 123.45 ); asp.net generate qr code QR code MVC html helper - NET 9 Oct 2017 ...

NET , C#, VB.NET, and IIS applications. In the first case, there really is no way to break the coupling, short of redesigning A. If A is derived from B, it was probably designed that way for a reason. If you didn t design A yourself, you might want to think twice before refactoring A s ancestry. Changing the base class of a class is not something you should attempt without proper forethought, especially if the sole goal is to reduce coupling. Inheritance always causes UTC, and there is no way around it. In the second case, there are ways to change UTC into ATC. Let s look at a simple example, with a class A that does nothing except create an instance of B and invoke a method. Figure 1-43 shows the class diagram of the system.

The precision is an integrity constraint, whereas the scale is an edit. It is interesting and useful to note that the NUMBER type is, in fact, a variable-length datatype on disk and will consume between 0 and 22 bytes of storage. Many times, programmers consider a numeric datatype to be a fixed-length type, as that is what they typically see when programming with 2- or 4-byte integers and 4- or 8-byte floats. The Oracle NUMBER type is similar to a variable-length character string. We can see what happens with numbers that contain differing amounts of significant digits. We ll create a table with two NUMBER columns and populate the first column with many numbers that have 2, 4, 6, . . . 28 significant digits. Then, we ll simply add 1 to each of them: ops$tkyte@ORA10GR1> create table t ( x number, y number ); Table created. ops$tkyte@ORA10GR1> insert into t ( x ) 2 select to_number(rpad('9',rownum*2,'9')) 3 from all_objects 4 where rownum <= 14; 14 rows created. ops$tkyte@ORA10GR1> update t set y = x+1; 14 rows updated. Now, if we use the built-in VSIZE function that shows how much storage the column takes, we can review the size differences between the two numbers in each row: ops$tkyte@ORA10GR1> ops$tkyte@ORA10GR1> ops$tkyte@ORA10GR1> ops$tkyte@ORA10GR1> 2 from t order set numformat 99999999999999999999999999999 column v1 format 99 column v2 format 99 select x, y, vsize(x) v1, vsize(y) v2 by x; +DoSomething() X Y V1 V2 ------------------------------ ------------------------------ --- --99 100 2 2 9999 10000 3 2 asp.net create qr code QR Code generation in ASP .
